Can Arbitrators be tried u/s 219IPC

 I am afraid. An arbitrator is a private judge. As an arbitrator, he is neither, public servant, nor judicial officer. So the question of application of IPC 219 does not arise.

Questioning arbitrator on the ground of misconduct also is extremely difficult,if not impossible, since, he is your own chosen person (except court appoints one).

If arbitrator ignores your objections, did not give reasons, you have remedy under Sec 34 of the Act.

After all, one should understand the purpose of arbitration is to redressal of disputes in a quick, fair and no or less cumbersome way.  

Dear Sir,

As per definition of "Public Servant" u/s 21 IPC, Arbitrator is "Public Servant"
